AUTOMATIC RECORDING METER FOR LIQUIDS.

original No. 1,612,485, dated December 2a, 1926: Serial No. 623,140, filed March a, 1923, and in France March 10, 1922. Application for reissue filed May 28, 1927, Serial No. 195,132.

The invention relates to new and useful improvements in measuring devices used in connection with automatic recording meters for all kinds of liquids.

An object of the invention is to provide a measuring device of the above type having two measuring chambers of given capacity, and a reversing valvemechanism for con trolling the flow of the liquid alternately to and from said chambers, with means normally inactive for shifting the valves, and with means controlled by the pressure on the liquid in said measuring chambers for initiating the movement of said valves by said actuating means.

In the drawings which. show by way of i llustration one embodiment of the invention- Figure 1 is a section on the line AA of Fig. 2, through the measuring chambers and the controlling valve mechanism therefor;

Fig. 2 is a sectional view on the line B-B of Fig; 1, showing only the frame structure, and

Fig. 3 is a sectional view on the line CC of Fig. 1 with the valve mechanism removed.

The invention is directed broadly to a mechanism for measuring liquids, which is adapted to be used in connection with a recording meter. There are two'independent measuring chambers of a given capacity. There is a feed pipe for delivering liquid to said chambers and an exhaust pipe for discharging the liquid from said chambers. These two pipes are common to both chambers and between the pipes and the chambers is a reversing valve mechanism for controlling the flow of the liquid through said pipes. Associated with this reversing valve mechanism is an actuating means therefor, which is normally inactive and which operates to shift the valves and connect said chambers alternately with the supply and exhaust pipes. There is also means controlled by the pressure on the liquid in said measuring chambersfor initiating the movement of said valves by said actuating means. Thus it is that the valves are actually moved by the actuating means which is of sufficient strength to move the valves X ery quickly when thrown into operation and this actuatingmeans is normally inactive. When a chamber is full, the pressure on the liquid in the chamber operates a controlling means which initiates or starts the actuating means for the valves.

excluded, however,

Referring more in detail to the drawings, my improved measuring device includes two chambers 1 and 2, which are mounted on a suitable framework, indicated at 1 in the drawings, but which are entirely independent of each other. Mounted above the cham- "hers 1 and 2 are two glass tubes 18 and 19 which are associated, respectively, with said chambers. These glass tubes form sights. Said tubes are held against a lower bridge piece 7- soldcred' on the metal forming the chambers by means of a cap 20, in which cap are arranged valves 21 and 22 of very small lift and apertures, such as at 23, which allow the air forced out by one of the reservoirs during filling to flow into the adjacent reservoir which is at this moment being discharged. Washers 8 may be retained in haskets 24 and25 opening at the lower. part and having bearing slots in the upper part, whichwvashers by their number and volume enable a precise and definite volumetric regulation of the two measuring chambers 1 and 2 to be effected.

The valves 21 and 22 are closed by the liquid when the chambersv are filled. Any

small quantity of liquid thrown out at the moment of release through the seats of the valves 21 and 22 and the hole 23 is collected in a chamber 27 and the overflow pipe 26 provides for the recovery of this liquid. It is from the measuring chamber and is not delivered'with the contents of the chamber. A small air admission valve 28 (see Fig. 2) allows external air to enter the chamber 27 and thus to pass into the measuring chambers, so as to provide for the emptying of both chambers when drawing off the liquid. The liquid is drawn off through an exhaust pipe attached to the opening in the frame at 12. There is a dis-' charge port 13, connected with the chamber 1, and this discharge port 13 extends down through the frame, and connec ts with a chamber 14 which leads to theopening 12 and the exhaust pipe connected therewith. There is also adischarge port 15 which connects with the chamber 2, and which also extends down through the frame and connects with the chamber 14. These ports 13 and 15 have been referred to as discharge ports and they are discharge ports when the chambers 1 and 2 are emptying. They are also filling ports when these. chambers are being filled. In

other words, the lower end of the port 13 is connected to a cylindrical port (see Figs. 1

and 3) which in turn is connected to the port 10. On the other side of the valvecasing,

indicated at 31 in Fig.'3, is a cylindrical port 32, which likewise connects with the port 10. This port 10 in turn connects with an opening 17 in the casing, which is connected to a receiving or filling pipe. The valve 9, shown in the drawings, is for the purpose of closing. the filling pipe when it is desiredto measure less than. a full capacity of the measuring device. This is not a part of the present invention and further description thereof is not thought necessary. I

The liquid flows into the chamber l'th'rough the port 30, and the port 13, and-flows out of said chamber tt'it ithe port 13 andchamber 14; A cylindrical valve 3, see 1Fig. 1, is

adapted to fit into the cylindrical 'port 30, and close theports leading to the filling 1pc,

or fit into the chamber on the othersi e of the lower end of the port 13, and close the outflow of the liquid from the chamber 1.

Likewise, there is a cylindrical valve 3 which fits in the cylindrical port 32 and prevents the inflow to the chamber 2, and likewise fits in a cylindrical opening at the lower end the port- 15 which leads to the chamber and" f prevents the outflow through .the pipe These two valves 3' and 3 'a're mountedon the same stem, indicated at 33 in the draw ings; lVhen said stem is reciprocated the valves may be moved IEI'OI'ILI). position where they cut ofl? the filling of one chamber to aposition where they will cutoff the fillingof 'the other chamber, and durin this move ment, when they cut off a cham er from the H filling pipe, they open said chamber to-the exhaust pipe.' The valve stem 33 is connected to the lower end ofa lever 6, see Fig. 1, which I is pivotally mounted ate, on a bracket 6', carried by the frame of-fthe measuring apparatus. There is a second lever 5, prefera I mounted on the same pivotal support 6. spring 6 is pivotally connected at its lower end to the lever 6, adjacent its, connection with the valve stem 33. and is connected at its upper'end' at 16 to the upper end of the lever 5.

Between the ports 13 and 15 the frame of the apparatus is provided with a cylindrical recess 34. Located in this-recess is a reversing piston 4. Said reversing piston is carried by a stem 35 extending out through the wall in the casing and said stem is connected to the lower end of the lever 5. The stem has an enlarged head 36, withv a vertical slot in which the pin 37 ,,carried by the lower end of the lever 5, engages. The ports, as-shown in Fig. 1, are so positioned that the chamber 1 is filled with liquid from the supplypipe. When the chamber is entirely filled, the valve 21 will be closed by theliquid. It is understood, of course, that the liquid is forced into the chambeig and therefore, the liquid will be put under a certain pressure when the chamber closes and is entirely filled. This pressure on the liquid will be transferred to the piston 4 and will move said piston to the right, as viewed in Fig. 1. Such a movement of the piston 4 will cause the lower end of the lever 5 to move to the other side of the pivot 6 -that is, take an angular position, which is just the reverse of that shown. in Fig. 1. As soon as this lever is on the other sideof the fulcrum pivot 6, the spring is positioned so as to pull on the lower end of the lever 6 with a pull which tends to swing the .lever 6 to the left, as viewed in Fig. 1, and this will shift :the valves 3 and 3 on to the other valve seats. While this, chamber '1 isbeing filled thechamber 2 is empt ing I as the port 32 is open. The shifting o the valve stem, however, through the actuation of the spring'will connect the chamber l'with "the exhaust pipe and will at the same time connect the chamber 2 to the filling pipe, so it is that these chambers are alternately connected with the filling and exhaust .pipes. The spring movesthe valve andis an actuating mechanism for accomplishing this pur- 1 pose. This spring, or actuating mechanism ormed thereby, is normally 1nact1ve,how-

ever. That is, whenthe arts are in the posit on shown in Fig3i1,,t e spring is -'on the right of the pivotf'pin 6, and therefore, the

lever vfi cannot be-Qf-urther moved thereby. It has reachedtheiextreme of its movement to the right. .The actuating jinechanism, will stay thus inactivenntil this piston 4 moves the lever 5, so as, to carry the upper end thereof "to the oth'e'r'vsideof the pivotal support 6". 'Bhen it isjthat the spring is so positioned astomove the'valve'in the opposite direction.

valve is moved by an actuating mechanism, including a; spring, which is normallyv in active, and the movement of this spring is initiated by the piston 4, which in turn is operated by the pressure on theliquid when the chamber is full. l-have, therefore, an actuating mechanism ready to shift the valve, but which willfnot operate until the chamber is filled and enough pressure is put on to the liquid in the chainber to cause the controlling It will be noted, therefore, that I have here; a reversing valve mechanism wherein the means to initiate the valve actuatingmechaing said chambers, each chamber having a vent and 'means for closing said vent after the means is provided for initiating the movement of the reversing valves.
